1. What are BJT arrays used for?
BJT arrays are often used in analog circuits like amplifiers, switches, and oscillators where matched transistor pairs are required for balanced performance.
-
2. What is a pre-biased BJT array?
Pre-biased arrays have integrated resistors, simplifying circuit design and reducing external component count, ideal for switching or logic applications.
-
3. What are the limitations of BJT arrays?
While they save space, they can limit flexibility if specific transistor types or configurations are needed. Also, thermal coupling might not always be beneficial in all scenarios.
-
4. How do BJT arrays compare to MOSFET arrays?
BJT arrays are preferred for applications requiring high current gain and faster switching, while MOSFETs are better for low-power and high-efficiency applications.
